Specification of ietters Patent.

Patented A1102 23, 1921.

Application filed December'2, 1920. Serial No. 427,772.

To all 'w /Lomy t may concern Be it known that we, HUGH lV.' SANFORD, .CHARLES A. GnrrriTH, and GEORGE E. JONES, Jr., citizens of the United States, residing at the city of Knoxville, in the county of Knox and State of Tennessee, have invented a new and useful Improvement in Railway-Cars, of which the 'following is a specification, reference being had to the accompanying drawing.

Thisinvention Arelates to an end sill for a car adapted particularly for mining purposes, and the Object of the-invention is to provide an integral casting which extends entirely across the end of the car to form an end sill, to act as a draw bar, to form the usual bumper, and to provide an effectual means for connection with the usual longitudinal sills thereby stiening and preventing the frame from twisting out of its rectangular shape and giving extreme rigidity to therconstruction.

The invention relates to a structure of this kind which will be hereinafter more particularly described and then definitely claimed.

ln the drawings accompanying and forming part hereof:

VFigure l is a top plan view of a draw bar bumper and end sill made in accordance with our invention. Y

Fig. 2 is a front elevation with parts broken away.

Fig. 3 is an end view.

Fig. 4 is a section through the line 4-4 of Fig'. l. v

Referring now to the details of the drawings by letters: A represents an end sill having a bumper B projecting outwardly therefrom,` a draw bar element D also projecting outwardly from said end sill and located over said bumper, trusses E, corner stiffeners F and Gr, and gusset stiffeners H and I, all preferably formed of one integral casting.

The aforesaid bumper B is swelled outwardly as indicated in Fig. l of the drawing, as is customary withbumpers of this class and located immediately over the central portion of the bumper is the aforesaid draw bar element D provided with a coupling pin opening D1 which is directly over a similar opening- B1 of the bumper, a soace being left between the draw bar D and the bumper B for the reception of a coupling link, the couplingpin being designed to drop through the openings D1 and B1.

The corner stiifeners F and G, which have been described as being part of the integral casting, are adapted to be securely riveted to the usual longitudinal sills J and J1, the latter being cut away as shown at J2 to afford space for the gusset stiffeners H and I.

From the foregoing and the accompanying drawings it will be seen that we have provided a one piece steel casting going entirely across the end of the car to provide an end sill, to act as a draw bar, to form the usual bumper, and to provide an eiiectual means for connection with the usual longitudinal sills. By this construction the structural steel side sills are rigidly braced against twisting and against an end shock as well. This arrangement also provides a stiffened device in the way of a corner angle which is an integral part of the end sill to run back alongside of the structural steel sills and tie the whole construction together in a rigid way against twisting, etc. Not only does the one piece casting provide the rounded bumper, the truss construction for the end, thedraw bar for the coupling pins, but the angle members or stiffeners prevent the frame from twisting out of the rectangular shape and gives extreme rigidity to the construction.

lVhat we claim as our invention is:

l. In a structure of the kind described, a one piece casting comprising an end sill, a bumper projecting therefrom, a draw bar element, and corner stitl'eners for connection with the longitudinal sills, Substantially as described.

2. In a Structure of the kind described, a one piece casting comprising an end sill, a bumper projecting outwardly therefrom and having a. coupling pin opening, a. draw bar element also projecting outwardly from said end sill and having a coupling pin opening in line with the coupling pin opening of the bumper, and corner Stifleners having connection with the longitudinal sills, substantially as described.

3. In a structure of the kind described, a one piece casting comprising an end sill, a. bumper projecting outwardly therefrom and havingtrussed members connecting it with the sill, a draw bar element also projecting outwardly from said end sill, and corner stiiieners for connection with the longitudinal sills, substantially as described.

l. In a structure of the kind described, a one piece casting comprising an end sill eX tending entirely across the end of the car and having corner stiffeners for connection withthe longitudinal sills, a bumper projectiiig outwardly from said end sill and having trussed members connecting with said sills and also having a coupling pin opening, a draw bar element also projecting outwardly from said end sill and extending over said bumper and having a coupling pin opening in line with the coupling pin opening of the bumper, substantially as described.

5. ln a structure of the kind described, a one piece casting comprising an end sill extending entirely across the end of the car and having corner stiffeners for connection with the longitudinal sills, a bumper projecting outwardly from said end sill and having trussed members connecting` with said sills and also having a coupling pin opening, av

draw bar element also projecting outwardly from said end sill and extending over said bumper and having a coupling pin opening in line with the coupling pin opening of the bumper, and gusset stiifeners between the` end sill and said corner stiifeners, substantially as described.

6. ln a structure of the kind described and in combination with the longitudinal sills, a one piece casting comprising an end sill extending across the end of the car from one of said longitudinal sills to the other, a bumper projecting therefrom, a draw bar element, and corner stiifeners integral with the end sill and forming a connection between said sill and said longitudinal sills, substantially as described.

7. In a structure of the kind described and in combination with the longitudinal sills, a one piece casting comprising an end sill extending across the end of the car from one of said longitudinal sills to the other, the ends of said sill having corner stiffcners for connection with said sills providing a rigid frame to prevent twisting, a bumper formed integral with said end sill and projecting outwardly therefrom and a draw bar element also formed integral with said sill and projecting outwardly therefrom over the aforesaid bumper, substantially as described.

In testimony whereof we have signed our names this 27th day of November, in the year one thousand nine hundred and twenty.
